In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
Capacitor banks play a pivotal role in substations, serving the dual purpose of enhancing the power factor of the system and mitigating harmonics, which ultimately yields a cascade of advantages. Primarily, by improving the power factor, capacitor banks contribute to a host of operational efficiencies.
Figure 5: Capacitor Banks at a Substation However, the employment of capacitor banks at substations stands as their most important application. They are also used in various other applications, though their size might change according to the size of the system. Cars: These banks are used in electric or hybrid vehicles to store electricity.
Capacitors are the most important part of capacitor banks, as their name implies. When needed, these capacitors release the electrical energy they have stored. These capacitors are connected in series and/or parallel to increase the total capacitance and energy-storing capacity. Resistors are among the most crucial components in a capacitor bank.
Power factor correction capacitor banks can be configured in the following ways: Delta connected Bank. Star-Solidly Grounded Bank. Star-Ungrounded Bank. Go to Content ↑ 1. Star-Solidly Grounded Initial cost of the bank may be lower since the neutral does not have to be insulated from ground.
The classification of the substation by nature of functions is explained below in details. Step-up or Primary Substations – Such types of substations generate low voltage like 3.3, 6.6, 11, or 33kV. This voltage is stepped up by the help of a step-up transformer for transmitting the power over large distances.
